.... The operational requirements to precisely and successfully cut the packer's release mandrel often limit the use of traditional mandrel cutting techniques. Advancements in electromechanical pipe cutting technology address the need for a precise, successful cut of the packer mandrel. As a result, downtime, risk...

.... This paper advances the analysis of more than 400 tubing straddles set since 1985. SPE paper 104055 showed that the majority of straddles were installed over damaged gaslift valves and gaslift mandrels. Damage to a gaslift valve can occur when it is eroded (or flow cut) due to fluid unloading of the casing...

.... Then, the HST and second KOT were used to successfully install the new GLV into the mandrel. The operator is now able to optimize their gas lift design without the limitations imposed by conventional means for installing GLVs such as slickline and coiled tubing. This allows them to place gas lift valves...
